Definitions

  • the present invention relates to a joining head arrangement for joining components to workpieces, and to a method of feeding a component to a component holder and of joining the component along a joining axis to a workpiece according to the preamble of claims 1 and 10 respectively (see, for example, US 6 018 863 ).
  • a joining head arrangement is known from document EP 1 495 828 B1 .
  • joining is intended in the present context to relate to all connecting methods of elements such as fastening elements to workpieces, such as metal sheets, including adhesive bonding, forming, such as riveting for example, or combining of materials, such as welding for example.
  • joining is intended in the present case to relate to the joining of rotationally symmetrical components, such as studs, to workpieces, which are to be connected to the respective workpiece, for example, by short-time arc welding (stud welding) and/or by thermoplastic connecting processes such as thermoplastic adhesive bonding or thermoplastic welding.
  • the components can be studs which have a shank and a head or flange section having a somewhat larger diameter than the shank.
  • singulated studs are fed to the joining head arrangement by compressed air.
  • the stud holder is designed as a collet which can be expanded to a diameter equal to at least the flange diameter.
  • the studs are fed from the rear, with the flange section in front, into the holding device until the flange section emerges axially from the collet and the collet still holds the shank of the stud.
  • a stud welding operation can then be carried out, which can comprise the steps of putting the flange section onto the workpiece, directing a pilot current through the stud and the workpiece, then lifting the stud from the workpiece in order to draw an arc, switching over to a welding current, such that those surfaces of the flange section and the workpiece which are opposite one another are fused, and finally lowering the stud onto the workpiece again until the arc is extinguished.
  • the welding current is switched off approximately at the same time, such that the complete melt pool solidifies and the stud is integrally connected to the workpiece.
  • a problem with the above joining head arrangement is that the component holder is subjected to considerable wear. This is due to the fact that the elastic damping elements of the component holder are overstretched by the relatively large cross section of the flange section.
  • a further joining head arrangement is known from document DE 102 23 147 A1 .
  • a housing on which a slide is mounted in a linearly movable manner is mounted on an elongated arm in a rotatable manner.
  • the feed device is fixed to the arm and ends in a transfer station.
  • the housing can be rotated with respect to the arm in such a way that a stud readied at the transfer station is received there in order to subsequently carry out a joining operation with the received stud and after rotation back into a joining position.
  • the cycle times are relatively long.
  • the component holder is designed relatively complex in order to be able to reliably receive the stud readied at the transfer station.
  • Further joining head arrangements according to the preamble of claim 1 are shown in document US 6 018 863 A and US 2007/0067975 A1 .
  • document US 3 658 230 A shows an automatic blind riveting machine comprising a pivotable head.
  • the object of the invention is to specify a joining head arrangement and a joining method with which relatively short cycle times can be achieved.
  • the above object is achieved by a method of feeding a component to a component holder and of joining the component along a joining axis to a work-piece as defined in claim 10.
  • a transition of a welding current line from the slide to the hinged element is designed in such a way that the welding current line is disconnected when the component holder is located in the transfer position and closed when the component holder is located in a joining position. This ensures that the hinged element is free of welding current in the transfer position.
  • At least one feed device for feeding the component is provided, wherein the component is transferred at a transfer location from the feed device to the component holder, and the joining axis runs in such a way that the component holder can be pivoted between the transfer location and a joining position.
  • the component holder can be of very simple design. This applies in particular when studs having a flange section are joined. Said studs can be transferred with the shank in front into the component holder, such that overstretching of the stud holder can be avoided. The service life of the component holder can be substantially prolonged as a result.
  • the transfer location is fixed with respect to the housing or the slide. It is especially preferred to fix said transfer location to the housing, since the feed device consequently does not have to be moved along in the region of the transfer location.
  • a shaft is rotatably mounted on the slide, the hinged element being fixed to said shaft.
  • the shaft in this case forms the pivot axis.
  • the rotation of the hinged element for example by rotating the shaft, can be realized in a simple manner from a design point of view.
  • the drive device has a pneumatic cylinder or the like.
  • the drive device can have an electric motor, which can be designed as a stepping motor for example.
  • the electric motor is arranged concentrically to the shaft.
  • an output shaft of the electric motor can be connected directly to the shaft to which the hinged element is fixed.
  • the transition of the welding current can advantageously be provided by means of an electric contact spring-preloaded in the direction of the hinged element.
  • the spring-preloaded contact makes a connection between the hinged element and the welding current line, wherein the connection provides a reliable current transfer and at the same time can be released and closed again in a simple manner and without wear.
  • the contact is preferably covered by the hinged element, such that it cannot be contaminated by weld spatter.
  • a sensor device which, in the transfer position, determines by means of an auxiliary voltage whether a component is present in the component holder.
  • the component holder in particular a chuck of the component holder, may comprise two segments electrically isolated from one another at least before the insertion of a component.
  • the hinged element is disconnected from the welding current line. Therefore the shaft which is rotatably mounted on the slide and to which the hinged element is fixed is designed to be electrically conductive in order to be able to apply the auxiliary voltage in a simple manner from the design point of view when the component holder is located in the transfer position. If the auxiliary voltage is applied and a metallic component, for example a stud, is located in the component holder or the chuck, a test current now flowing on account of the application of the auxiliary voltage can be detected by the sensor device.
  • the component is fed continuously through the feed passage into the component holder.
  • no transfer station is provided at which the component stops and is then "fetched" by the respective component holder.
  • a stud can be transferred directly, without an intermediate stop, into the component holder, for example by compressed air or the like.
  • the component holder can be designed in a simple manner, for example as an essentially cylindrical collet into which a shank of the stud is inserted.
  • a cylindrical stud holder can be formed with at least one longitudinal slot, preferably with a plurality of longitudinal slots, in order to provide the requisite radial elasticity.
  • At least one further component can be held ready at the transfer position.
  • the component is then not fed continuously.
  • a joining operation and a feed operation can be carried out essentially in parallel.
  • a joining system is designated generally by 10 in Fig. 1 .
  • the joining system 10 is designed for stud welding by the drawn arc method.
  • the joining system may also be designed for other joining processes, such as, for example, thermoplastic welding or adhesive bonding.
  • the joining system 10 contains a robot 12 having a fixed base 14, on which a first arm 16 is mounted in an articulated manner, on the free end of which arm 16 a second arm 18 is mounted in an articulated manner.
  • a joining head arrangement 20 is fixed to the free end of the second arm 18.
  • the joining head arrangement 20 may also be part of a manually operable welding gun or the like.
  • the joining head arrangement 20 can be moved to various locations by means of the robot 12.
  • a joining system is used in motor vehicle technology, to be precise for joining studs to body sheets. Studs fixed to the body sheet in such a way can be used as anchors for plastic clips for fastening conduits or the like, or for latching attachments in place, such as panelling, etc.
  • the stud comprises a shank 26 and a flange section 28 having a larger diameter.
  • the stud is in this case joined to the workpiece 24 in such a way that the shank 26 projects approximately perpendicularly from a surface of the workpiece and can consequently serve as a fastening element, for example as an anchor or the like.
  • the joining head arrangement 20 contains a housing 30 which is fixed to the free end of the second arm 18.
  • a slide 32 is mounted on the housing 30 in a linearly displaceable manner.
  • Also provided on the housing 30 is a schematically shown linear drive 34, by means of which the slide 32 can be moved parallel to a guide axis 36 with respect to the housing 30.
  • the linear drive 34 may be an electric linear motor; however, the linear drive 34 may also contain a mechanical drive such as a spring.
  • a hinged element 37 is mounted on the slide 32 such as to be pivotable about a pivot axis 40.
  • the pivot axis 40 is skewed relative to the joining axis 36 and is oriented transversely, in particular perpendicularly, to the joining axis 36.
  • a component holder 38 in the form of a stud holder is fixed to the hinged element 37.
  • the hinged element 37 is located in a joining position in which the component holder 38 holds a stud 22', which is the next to be joined to the workpiece 24.
  • a feed device 42 for feeding components 22 to the joining head arrangement 20 is connected to a singulation device 44 in which components 22 provided as free-flowing material are singulated and are then delivered individually from the fixed singulation device 44 to the joining head arrangement 20, for example by compressed air.
  • the joining system 10 contains a supply device 46 which can provide, for example, a welding voltage and control signals for operating the joining head arrangement 20.
  • the supply device 46 is connected to a control device 52 in the housing 30 via a first cable harness 48.
  • the control device 52 can be connected to the base 14 of the robot 12 via a second cable harness 50.
  • the supply device 46 and the base 14 can also be connected to one another via a third cable harness 54.
  • the welding voltage required for the stud welding or the requisite welding current is provided via the first cable harness 48 and is directed to a contact 55 via a welding current line 53.
  • the contact 55 is preloaded in the direction of the hinged element 37 by means of a spring element 57, such that firm bearing of the contact 55 against the hinged element 37 is ensured when the hinged element 37 is located in the joining position. Furthermore, the movements of the robot 12 and of the slide 32 are coordinated with respect to the housing 30 via the cable harness 48 and via the other cable harnesses.
  • the component holder 38 is rotated into a transfer position in which the component holder 38 is aligned with the feed device 42.
  • the feed device 42 contains a feed passage 58, for example in the form of a flexible tube, through which the components 22 can be delivered to the joining head arrangement 20 by means of air pressure 56, as indicated by a component 22".
  • the feed passage 58 is fixed to the housing 30 and ends in the region of a transfer location 60.
  • the transfer location 60 is arranged in such a way that the component holder 38 can be aligned therewith by pivoting the hinged element 37 about the pivot axis 40. As a result, it is possible to deliver a component substantially continuously from the feed passage 58 by means of the compressed air 56 into the component holder 38 aligned therewith.
  • the stud is delivered with the shank in front into the component holder 38, such that the clamping elements of the latter need not be expanded to the diameter of the flange section 28.
  • the stud is then held in the component holder 38 by a radially elastic effect, as shown for the component 22' in Fig. 1 .
  • the feed passage 58 is in this case designed to be appropriately flexible, such that it can follow the movement of the housing 30 and thus of the transfer location 60.
  • the hinged element 37 together with the component holder 38 is subsequently pivoted into the joining position, as indicated by an arrow.
  • the joining position may be oriented, for example, diametrically relative to the transfer location, such that the hinged element 37 together with the component holder 38 is shifted by 180° about the pivot axis 40.
  • the component 22' is then already held in the correct position, such that the slide 32 can subsequently be shifted with respect to the housing 30 in order to put the component 22' onto the surface of the workpiece 24.
  • a pilot current is then directed through the contact 55, the component holder 38, the component 22' held thereon and through the workpiece 24.
  • the component 22' is lifted again from the surface of the workpiece 24 by means of the slide 32, such that an arc is struck.
  • the electric current is then increased to a welding current, which may be within the region of > 1000 A.
  • a welding current which may be within the region of > 1000 A.
  • those surfaces of the component 22' and of the workpiece 24 which are opposite one another are fused.
  • the slide 32 is then lowered again onto the workpiece 24 by means of the linear drive 34, such that the molten pools intermix.
  • the welding current is switched off.
  • the complete molten pool solidifies, such that the component 22' is then integrally connected to the workpiece 24.
  • the slide 32 is then moved back, and the hinged element 37 together with the component holder 38 is rotated again into the transfer position in order to receive a new component 22".
  • a joining operation in the form of a stud welding process is then carried out again.
  • the hinged element 37 is fixed to a shaft 62 which is rotatably mounted on the slide 32.
  • a pneumatic cylinder 64 which is indicated schematically in Fig. 1 , can be provided for pivoting the hinged element 37.
  • a drive device can be formed by an electric motor 64' which is arranged concentrically to the shaft (as indicated schematically in Fig. 2 ).
  • the shaft 62 which is rotatably mounted on the slide 32 and arranged concentrically to the pivot axis 40 is preferably electrically conductive.
  • an electrically conductive connection is provided between the sensor arrangement 66 and the shaft 62.
  • the component holder 38 comprises at least two segments which are electrically isolated from one another and which are each electrically conductive, such that an auxiliary voltage for checking for the presence of a component 22 in the component holder 38 can be applied via the shaft 62 and the component holder 38.
  • a sliding contact can be provided, or a contact arrangement which can be closed and released can be provided, such that a contact is always made when the hinged element 37 is located in the transfer position.
  • the transfer of the welding current to the hinged element 37 and the component holder 38 is effected as described above by means of the welding current line 53 and the contact 55.
  • a sliding contact or a contact arrangement to be provided for transferring the welding current from the housing 30 or the slide 32 via the shaft 62 to the hinged element 37 and the component holder 38. Said contact arrangement can then be closed and released in such a way that a contact is always made when the hinged element 37 is in a joining position.
  • FIG. 3 Shown in Figure 3 is a further embodiment of the joining head arrangement according to the invention, which generally corresponds to the joining head arrangement 20 of Fig. 1 with regard to construction and functioning. The same elements are therefore provided with the same designations. The differences are essentially explained below.
  • the joining head arrangement 20 has a rigid elongated arm 70, on the end of which a housing 30 is mounted such as to be rotatable about a head rotation axis 72.
  • a slide 32 can in turn be moved on the housing 30 such as to be axially displaceable parallel to the joining axis 36, as in the above embodiments.
  • This arrangement offers the advantage that the housing 30 can be pivoted together with the slide 32 about the head rotation axis 72 in order to enable components 22 to be joined even in positions where access is difficult.
  • the components 22 are fed along the arm 70 via the feed device 42. There, the studs or components 22 are stopped and readied in a transfer station 69 located at the transfer station 60, as shown in Fig. 3 for the component 22"'.
  • the hinged element 37 is pivoted about the pivot axis 40 into the transfer position and if need be the slide 32 is moved in such a way that the component 22"' can be transferred.
  • the components 22 can be fed into the component holder 38 in two steps, that is to say not continuously. First of all, a component is fed into the transfer station 69. In a second step, the component is transferred from the transfer station 69 into a respective component holder 38. A corresponding mechanism is to be provided for this purpose. If need be, the transfer in the component holder 38 can also be effected by the component holder 38 being aligned with the transfer station 69 and then by the slide 32 being moved in order to push the respective stud holder onto the component 22 readied at the transfer station 69.
  • the component holder 38 may also be designed as a collet which in the opened state can be directed over the shank of a component 22 which is readied in the transfer station 69.
  • the first step can be carried out while a joining process is being carried out and the component holder 38 is located in a joining position, and therefore the number of cycles of the joining system 10 can be increased by this parallel procedure.
  • the components 22 may of course also be fed continuously into the component holder 38 by the hinged element 37 first of all being pivoted into the transfer position and by the component 22 then being delivered continuously through the feed passage 58, for example by air pressure 56, into the component holder 38 arranged on the hinged element 37.
